Abstract: A SERVICEABLE VALVE CONSTRUCTION                Abstract of the Disclosure A serviceable valve is provided for controlling the recirculation of exhaust gases within an internal combustion engine.  The valve includes a housing having a first section provided with an interior chamber and a second section secured to and subtending said first section.  A diaphragm is affixed to and interposed the housing sections and is in communication with the chamber.  In response to a predetermined chamber pressure, the diaphragm is distorted in one direction from a predetermined rest position.  The housing is mounted on a fitting, which subtend the housing second section, whereby said housing and the diaphragm are rotatable as a unit about an axis of the fitting to selected positions of adjustment.          The fitting is removably mounted on the engine. Carried on the diaphragm is a stem assembly which is movable longitudinally in response to the distortion of the diaphragm.  A portion of the stem assembly extends through and protrudes from the fitting and has a valve piece mounted thereon.  The valve piece is adapted to coact with a valve seat disposed within a recircula-tion flow path of the engine exhaust gases and, when seated thereon, blocks recirculation of the exhaust gases through the engine.  The housing first section is provided with a port offset from the fitting axis and adapted to be removably connected to a pressure fluctuating segment of the engine.          Means is provided which coacts with the fitting and the housing second section and releasably retains the housing and diaphragm in a selected position of adjustment relative to the fitting.

Abstract: ABSTRACT        Solidification of colloidal argillaceous matter in essentially non-settling, aqueous slime media into a solid stable matrix is accomplished by mixing such slime with a hydratable calcium sulfate and hydrating to form an inter-locking strength bearing matrix.  The method is particularly useful for coalescing phosphatic clay slimes with hydratable calcium sulfate prepared from the co-produced waste phos-phogypsum.

Abstract: ABSTRACT OF THE DISCLOSURE           A level winding apparatus for coiling elongated material, such as wire or tube, into a compact coil. A non-contacting device located near a spooling arrangement for coiling consists of at least two parallel spaced-apart arm arrangements each located on either side of the material as it is wound onto a spool.  Each arm arrangement is adjustable to accommodate the transverse dimension of the material and carries a photoelectric control unit having fiber optic carrying cables connected to transmitter and receiver means for creating a high intensity light field extending at least a length to accommodate a range of paths of travel the material takes from the feeding means to the spool starting from an empty spool to built-up-of the coil.  An undesirable approach angle of the material onto the spool is detected and a correction is made so that the formed coil contains a number of superimposed layers each with a number of evenly and closely abutting adjacent windings.

Abstract: Abstract In a fluid metering  system,  a plunger actuated syringe is coupled to at least one source of fluid, and a highly accurate  friction drive is  coupled to the plunger for moving fluid to a delivery outlet.   The friction drive comprises a rack having a flat side and a rotatable circular drive shaft, or pinion, pressed against the flat side of the rack for moving the same by friction.  Opposed guide rollers engage the rack in opposition to the flat side in straddling relation with the  pinion  for  urging  the  rack  thereagainst.   A movable swing arm supports one of the guide rollers against the rack.  A spring leverages the swing arm and guide roller against the rack and transmits the force to  the pinion.   Means  is  provided  for  securing the swing arm and the movable guide roller  in a plane perpendicular to the flat side of the rack to prevent lateral  motion  of  the  rack  and  pinion  whereby inaccuracies in the system may be minimized.

Abstract: ABSTRACT OF THE DISCLOSURE A data reduction system is disclosed which includes an analog to digital converter for converting an analog signal to digital sample signal form, a digital compression filter for compression filtering the digital sample signals, and an encoder for truncated Huffman encoding the compression filter output.  A decoder for decoding the encoded signal, a digital reconstruction filter for decompression filtering of the decoded signal, and digital to analog converter means are included to reconstruct the analog signal.  The digital compression filter has a transfer function which includes zeros on the unit circle in the Z-plane at substantially zero degrees from the origin, while the digital reconstruction filter has poles on or inside the unit circle in the Z-plane at substantially zero degrees from the origin.  The transfer function of the digital compression may also include zeros on the unit circle in the Z-plane at at least one of the following pairs of angles, +41.41, +60°, +90°, +120° and +180°, in which case the transfer function of the digital reconstruction filter includes poles on or inside the unit circle at corresponding angular positions.  The poles of the reconstruction filter may be momentarily movable inwardly inside the unit circle in response to a detected error signal to speed recovery from such error signal.

Abstract: ABSTRACT OF THE DISCLOSURE:         An improved slide mount of the type comprising a flat rectangular pocket forming a slideway for receiving a standard slide film provided with two lateral rows of driving notches, a central window formed in the pocket and a deformable slot in communication with the slideway to allow the introduction of the slide film with its rows of notches perpendicular to the slot into the slideway.  This slide mount is improved in that at least one sprocket is provided for inside the slideway so as to engage one of the notches of the film and lock the same inside the slide-way.  This sprocket is smaller in size than the notch it engages to let the film free to expand to a certain extent when subjected to the heat of a lamp.  This improvement advantageously allows processing and handling of slide films and slides with less risk of damage to the films and less annoyance to the slide manipulators.

Abstract: ABSTRACT OF THE DISCLOSURE           A conveyor chain trackway to receive a chain.          The chain has first and second links, the latter alter-nating with the first.  Each first and second link comprises a pair of spaced side members.  There is a pivotal joint between neighbouring links.  Spikes are formed on a plurality of first links to receive and locate a load.  The trackway comprises a base member in the low friction layer on the base member and dimensioned to receive the second links.  Side plates are spaced from each side of the base member.  The side plates extend upwardly to be alongside the chain when the chain is in position.  The side plates can be adjusted on the base to vary the distance from the base.  Low friction distance pieces on the inner side of the side plate extends to contact and locate the chain.  The chain is thus held on a fixed course and movement inwardly of the low friction distance pieces can compensate for wear in the chain.
